SEAT-FRAME ron BARBER-CHAIRS.

Specification of Letters Patent.

Patented Apr. 20, 1920.

Application filed March 31, 1919. Serial No. 286,355.

To aZZ whom 'it may concern:

Be it known that I, WALTER F. KOKEN, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulImprovement in Seat- F rames for Barber-Chairs, of which the followingis a full, clear, and exact description, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to chairs of the kind that are used by barbers,dentists and other specialists, and particularly to barber chairs of thetype which are provided with a metal seat frame.

The metal seat frames that have heretofore been used on barber chairswere formed either by one large, heavy casting or a cast metal spidercombined with a cast metal member that formed the exterior portion orexposed portion of the seat frame. Metal seat frames of the characterreferred to are exceptionally heavy and are costly to manufacture onaccount of the large amount of machine work required in boring holes inthe casting and in grinding off the outer surface of the castingpreparatory to finishing it in porcelain enamel.

The object of my invention is to provide a seat frame for barber chairs,dentist chairs and the like that is light in weight and inexpensive tomanufacture.

To this end I have devised a seat frame that is composed of a supportingstructure formed preferably of wood and a sheet metal shell that incasessaid supporting structure and forms the exterior or exposed portion ofthe seat frame.

Figure 1 of the drawings is a vertical transverse sectional view of aseat frame for barber chairs and the like constructed in accordance withmy invention, said View chair and B the vertically-adjustable stem thatcarries the seat frame of the chair. The seat frame comprises asupporting structure of skeleton design formed preferably by ahorizontally 'disposed wooden member l secured to the stem B, aplurality of transversely-disposed wooden members 2 (only one of whichis shown in Fig. 2) arranged at right angles to the member 1 andconnected to same by screws 3 or other suitable fastening devices, and aplurality of rim pads or sections 4 mounted on the members 2 and securedto same in any suitable manner. The exterior or exposed portion of theseat frame is formed by a sheet metal shell composed of ahorizontallydisposed plate' mounted on the pads or sections 4 of thesupporting structure and a sheet metal skirt member 6 that surroundssaid plate and projects downwardly from same far enough to conceal themembers 1 and 2 of the supporting structure. The plate 5 is provided atits inner edge with a downwardly turned portion or depending iange 7that laps over the inner edge of the sections 4, and said plate projectslaterally some distance beyond the outer edge of said sections and isbent downwardly and inwardly so as to form a bead 8. The skirt member 6of the shell is provided at its upper edge with an inwardly-projectingflange 6a that is preferably set into recesses or grooves -in thesections 4, said skirt member 6 being secured to the supportingstructure preferably by screws or other suitable fastening devices 9, asshown in Fig. 1. The lower edge of the skirt member 6 is bent to form abead 10.

A seat frame of the construction above described is light in weight, asit is composed of a supporting structure of skeleton form incased by asheet metalshell that forms the exterior of the seat frame. Furthermore,such a seat frame can be manufactured at a low cost, owing to the factthat the sheet metal shell of same can be formed in a die press and canbe finished in porcelain enamel without the necessity of first grindingofi' the surface of same that is to be coated with enamel.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

1. A seat frame for barber chairs and the like composed of a supportingstructure, a sheet metal skirt member surrounding said supportingstructure and depending from same, and a sheet metal plate mounted onsaid supporting structure and projecting laterally over the upper edgeof said skirt member.

2. A seat frame for barber chairs and the like composed of a skeletonsupporting structure formed by a plurality of Wooden Lesmo@ members, anda sheet metal shell incasing said supporting structure and composed of avertically-disposed skirt member, and a horizontally-disposed top plateWhose peripheral edge is .bent to form a finishing bead that surroundssaid Skirt member.
